Title: Loose piece electrical terminals selectively plated and apparatus and method therefor
Inventor: SMITH MARK LORING
IPC: C25D5/02
Filed: 1984-11-07
Granted: 1988-11-24
Abstract: In the apparatus, loose-piece terminals (15) are fed (114) to a rotating mandrel (3), and are releasably secured by retaining means (132). The mandrel (3) has a plurality of anode extentions (29) and associated nozzles (26) therein. Said anode extensions are mounted for reciprocation into receptacle portions (118) of secured terminals (15). A conduit (36) supplies pressurised plating fluid through the nozzles (26), to the anode extensions (29) and into the receptacle portions of the terminals to enable selective plating of internal surface portions. Retaining means (132) is an elongate resiliently mounted member surrounding a portion (126) of the mandrel (3) to hold terminals (15) against the mandrel (3) during the plating process. After plating the anode extension (29) are retracted from the terminals (15), said terminals are thereafter released when they pass the end of retaining means (132). A terminal so selectively plated has an internal plating of at least 3.81 x 10<-><7> meters with edge margins of tapered thickness covering at least portions of sheared edges of the terminal.

IPC: C22C5/06
Filed: 1984-01-30
Granted: 1990-11-29
Abstract: Electrical contact materials based on AgCdO with CdO as the main active component have proven to be particularly advantageous for low voltage switchgear in the power industry. However, when switching AgCdO contact materials, CdO, which is classified as toxic, can escape into the environment through burn-off. It is important, therefore, to keep the CdO content as low as possible in the contact material, or to exclude it completely. The contact material according to the invention is a sintered contact material consisting of AgSnO2 with at least two other metal oxide additives; namely, Bi2O3, CuO and optionally CdO. Relative to SnO2, these additives Bi2O3, CuO optionally CdO, amount quantitatively to a total maximum of 25 percent by volume of the total amount of oxide.

Title: Method of manufacturing a pole body for an electric igniter, said pole body and its application
Inventor: WITTWER ALFRED
IPC: F42B3/10
Filed: 1985-05-15
Granted: 1987-12-23
Abstract: The pole body for electric fuses comprises a homogeneous insulator in which a needle-shaped detonator pin is arranged normally to the plane of a metal layer which contacts a detonator charge on its opposite side. Due to the nearly point-shaped detonating bridge formed in the metal layer there occur, at the moment of detonation, very high current densities which cause melting of the detonating bridge. The pole body is manufactured from a glass tube surrounded by a metal tube. In order to prevent occlusion of gas in the insulator formed from the glass tube, a guiding body is placed upon the tip of the detonator pin which is part of a pole pin or of a pole cup during the melting operation. Preferably, the pole body is used in fuses with extremely short reaction times, for example, in ammunition, projectiles and the like.

Abstract: The mechanism has a housing (32) containing a first annular cam face (36) around its axis (A). A body (40) with a second such face (42) turns on this axis, working against the first face so as to generate movement in the axial direction. A first screwed body (50), also rotating on this axis, engages with a second screwed body (60) acting on a brake shoe via an adjusting thread (62). A clutch (70) transmitting ilmited torque acts in one direction of rotation between the bodies so as to adjust the shoe, but allows the first body to turn in the opposite direction without moving the first screwed body. A resetting shaft (92) in the housing allows the screwed bodies to be turned back in relation to each other in order to change the shoe, and is lockable. The shaft is to the side of the housing axis, and is coupled by a gear train (88,90) to one of the screwed bodies.
